Peewee – Using MySQL


Peewee – Using MySQL



”;


As mentioned earlier, Peewee supports MySQL database through MySQLDatabase class. However, unlike SQLite database, Peewee can’t create a MySql database. You need to create it manually or using functionality of DB-API compliant module such as pymysql.

First, you should have MySQL server installed in your machine. It can be a standalone MySQL server installed from https://dev.mysql.com/downloads/installer/.

You can also work on Apache bundled with MySQL (such as XAMPP downloaded and installed from https://www.apachefriends.org/download.html ).

Next, we install pymysql module, DB-API compatible Python driver.


pip install pymysql

The create a new database named mydatabase. We shall use phpmyadmin interface available in XAMPP.


My Databases

If you choose to create database programmatically, use following Python script −


import pymysql

conn = pymysql.connect(host=''localhost'', user=''root'', password='''')
conn.cursor().execute(''CREATE DATABASE mydatabase'')
conn.close()

Once a database is created on the server, we can now declare a model and thereby, create a mapped table in it.

The MySQLDatabase object requires server credentials such as host, port, user name and password.


from peewee import *
db = MySQLDatabase(''mydatabase'', host=''localhost'', port=3306, user=''root'', password='''')
class MyUser (Model):
   name=TextField()
   city=TextField(constraints=[SQL("DEFAULT ''Mumbai''")])
   age=IntegerField()
   class Meta:
      database=db
      db_table=''MyUser''
db.connect()
db.create_tables([MyUser])

The Phpmyadmin web interface now shows myuser table created.
